A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?
Answers
Answer:
15
Step-by-step explanation:
Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.
To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2
Brainliest pls
The speed of the scooter is 15 feet per second.
To calculate the speed of the scooter in feet per second, you can use the formula:
Speed = Distance / Time
The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.
Plugging these values into the formula, we get:
Speed = 30 feet / 2 seconds
Speed = 15 feet/second
Therefore, the speed of the scooter is 15 feet per second.

(Least Common Multiple and Greatest Common Divisor)
Answers
Answer:
I got you lol
Step-by-step explanation:
Let's say you want to calculate the GCD and LCM of two numbers: 12 and 28. First, determine the prime factorizations of 12 = 2 × 2 × 3 and 28 = 2 × 2 × 7. The GCD is the string that is present in both sets of factorizations, i.e., 2 × 2 = 4. The LCM is the greatest power of all exponents; 2 × 2 × 3 × 7 = 84.
simply put, The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b.
GCD is the largest number that divides 2 numbers equally and gives remainder 0.

The height, h in feet, of a rocket is given by h=-16t^2+64t+190, where t is time in seconds. Find the maximum height of the rocket and find the time the rocket was in the air.
Answers
Step-by-step explanation:
The height, h in feet, of a rocket is given by, where t is time in seconds.
[tex]h=-16t^2+64t+190[/tex] ...(1)
We need to find the maximum height of the rocket and find the time the rocket was in the air. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
[tex]\dfrac{d(-16t^2+64t+190)}{dt}=0\\\\-32t+64=0\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]
So, it will reach its maximum height in 2 seconds.
Now put t = 2 in equation (1) as follows :
[tex]h(2)=-16(2)^2+64(2)+190\\\\=254\ \text{feet}[/tex]
So, the maximum height of the rocket and find the time the rocket was in the air is 254 feet and 2 seconds respectively.

The temperature in Australia is 95 degrees and decreasing at a rate of 4 degrees per day. The temperature in the US is 40 degrees and is increasing at a rate of 5 degrees per day. For how many days will Australia be warmer or the same as the US?
Answers
Answer:
For 6 days
Step-by-step explanation:
Here, we want to find the number of days at which Australia will have a bigger temperature or the same temperature as US
95 degrees, decreasing at 4 degrees per day
40 degrees, increasing at a rate of 5 degrees per day
let the number of days be x
In x days, temperature of Australia will be 95-4x
In x days, temperature of US will be 40 + 5x
For the temperature to be same;
40 + 5x = 95 - 4x
95-40 = 5x + 4x
9x = 55
x = 55/9
x = 6.111 which is approximately 6
For 6 days, the temperature in Australia will be warmer , on the 7th day, the US temperature becomes warmer

Answer:
The correct matches are;
All students at the university → Population
The proportion of the 300 surveyed students who are in-state students → Statistic
The list of the 300 answers to the survey question → Data
The answer in-state out-of-state or foreign → Parameters
The 300 students who were surveyed → Sample
The proportion of all students from this university who are in-state → Variable
Step-by-step explanation:
1) The population is the set that contains total number of possible observation in the question, the population is all the students of the university
2) A statistic is a calculated quantity derived from a sample's data value that can be used in estimating a parameter of the population or outlining a sample characteristic
The proportion of the in-state student in the sample is found by taking the ratio of the number of in-state student in the sample to the total number of student in the sample
3) Data are collected information which may be qualitative or quantitative variables
The answers collected in the survey are the data of the 300 surveyed student
4) A parameter is the value that is used as the means of measuring or classifying an item or system
5) A sample is a part or portion of a population, that serves as representative of the population
6) A variable is a quantity that can vary or cannot be said to be constant.
The number proportion of all students from the university who are in-state students can change due to change in the proportion during graduation and admission.
The vocabulary word when correctly matched to the corresponding example would give:

The student council made a pront of $3,000 on a car wash. If they invest the money at 5% interest
compounded yearly, how much money would they have in four years?
Answers
Answer:
$3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.
Step-by-step explanation:
We are given:
Principal Amount = $3000
Interest Rate r = 5% or 0.05
n=1 (compounded yearly)
Years t= 4
We need to find future value (A)
The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values in formula and finding future value A
[tex]A=P(1+\frac{r}{n})^{nt}\\A=3000(1+\frac{0.05}{1})^{1*4}\\A=3000(1+0.05)^4\\A=3000(1.05)^4\\A=3000(1.215)\\A=3375[/tex]
So, $3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.
